To all whom it may POINT/7t.

Be it known that l. liMAXI'l-IL J \UFIER( l il.

eitizen oi the United States of American residingat Brooklyn. in the count)! of Kings and State of New York. have invented new and useful Improvements in Hand-ope 'at-ed Signals, of which the followingis a speoith cation.

This invention relates to a device adapted to emit sound for alarm. signal or other purpose. and more partieularly to a hand-operated diaphragm horn especially for use onantomohiles, in which the sound is gen-- erated by rapid vibration of the diaphragm.

In greneral the ohjeet is the ronstrnetion of an improved derive of this elass. e: sy to operate. and always reliable and effective.

This is a division of my prior application filed May 251, 1919., Serial No. 7001375;

' In the arreompalrv'ing' drawing, illustrating one embodiment of the invention, l igure J. is a. sectional view, with parts in elevation; and Fig. l is a detail view illustrating a preferred form of enni teeth for the rotatable d i a plira gin-actuator.

3 is a suitable casing having an opening at one side or end elosed hya diaphragm 5 and a casing); member 6, the. diaphragm being lumped between said member 5 and a frameor clamping member l, to whieh latter the casing 33 is attached by any suitable means. The diaphragm 5, whieh ma he, such as eommonly employed in automobile horns, has at its eenter a heveled wear-piece ll adapted for eugagei'ncnt hy the teeth of a toothed rotor or dia ihragm-aetnator 10. A shaft 5.) iajo'arnaled to rotate in supports 7 and S, whieh may he braeket arms projecting from the part 4.

A ratehet wheel, 19 is secured rigidly to the. shaft 5), and a pawl .20 is adapted to engage said ratehet. Said pawl is carried by a sleeve-l1 loosely fitted on shalt Said sleeve 2] is rotated .in response to pull on the llowdenavire 13,: which latter is eun-.

' neeted to one end of a flexible steel hand It,

the other end of whieh eoils about and fastens to the sleeve 21. A coiled flat spring; 32 has one. end fastened to sleeve. Bland its other end secured to support 7. The Bowden wire has a,flel :ihle tubing 129 and extends-to a manually-aetuated member, here shown as a. reeiproeat ing lever .17 earried by,

a bracket 16, It will thus be understood that actuation of the lever 17, imparting a pull to the llowden wire 1.3, will operate' through the steel hand H and panl-andratrhet merhanism to rotate the shaft 9 in one direrlion. and that. as soon as the. Flowden wire is released. spring 22 w.ill return the Bowden wire. sleeve 21. and pawl 20 to their starting position. v

'liv increasing the weight of the dia- 1ihraQm-aetuator 10 with a lead member 18 or ther suitable means. the momentum given to said liaphragm-aetuator, or diaphragm-aetuating n'ieans. by the initial pull of the llowden wire. will eonlinue the rotation of said diaphragm-arluatorit], the spring 2; in the meantime returning sleeve L'l pawl 30. and llowden wire 3 to normal starting position, read)- for a new pull from the ilowden wire. 'ihespirallj. arranged spring 22 is rontmeted and expanded within its own plane. and has the. :ulvantageof its snseeptihili'tv ot' hein sr wom d up to av very suhstantial extentby a pluralitii of revolutions llllPllltlHl to the sleeve 31,116 as to produee a plurality of rr-xolutions of the shaft and diaphrag'm-m-tnator 10 for eaeh pull of the Bowden wire. I

in praetire. it is'lound that the weighted diaphraem-aetual'or l0 nets as an ellieient lt "lll.li()l of speed: it stores up some of the power of the sudden impulses imparted to it h the manual aetuating meansand gives out sueh power For a period eontinnin; he- \'o|u| the )eriod of positive. artoation oi themanual, means. and he! ween sueeeeding intermittent artual'ious of said manual means, thus tending to efieet uniformity of speed. The teeth of the diapliragrm-aet'uator ill vihratin u the diaphragm may he rounded at the tips. asshown in Fig, 2. The actuat r 10 operates in one du'eetion ol' rotation only,

and the teeth move with the. abrupt end Forward. in the. direeiion of the arrow ll'ith l'hisarraugemeut it will he tound that the time oi eoul'aethetween the diaphragm wear-pieeeand the aetuator -teetl'i' is nmeh lessened and the impulses imparted to the diaphragm will he more sudden. producing a more ellirient. warning! note.
